Add an ability to rotate the watermarked text
Would it be possible for you to add an ability to rotate the watermarked text? The user should have the ability to define how many degreed he wants to rotate the text in addition to horizontal and vertical spacing that exists right now.
This feature for example should be able to create the PDF file with a watermarked text going upwards from bottom left side of a page to top right.
I have sent a modified source code of version 1.1.7 with such ability to the WooCommerce support email (email@example.com). Feel free to reuse it.
